Understanding Sofa Sizing
Why Proper Sizing Matters
Choosing the right sofa size ensures comfort, proper room proportions, and successful delivery. A sofa that's too large overwhelms the space, while one that's too small looks lost and provides insufficient seating.
Key Considerations
- •Entry Points: Measure all doors, hallways, stairs, and elevators
- •Room Layout: Leave adequate walking space (24 inches minimum)
- •Comfort: Consider seat depth and height for your family
- •Proportions: Sofa should complement room scale
Calculation Method
Step 1: Measure entry constraints
Step 2: Frame height = min(door, stair, hallway) - 4"
Step 3: Max width = min(wall space - 24", lift height - 4")
Step 4: Seat width = total width - 12" (for arms)
Step 5: Match to standard sizes
Seat Depth Guidelines
- Tall People (6'+): 24+ inches depth, higher seat
- Average Height: 20-22 inches depth
- Shorter People: 18-20 inches depth, lower seat
- Lounging: 24+ inches for lying down
